8 1 Introduction 1.2 Description The Wtrans receiver T01 is used in conjunction with suitable Wtrans transmitters for mobile or stationary measurements of physical measurands. The use of advanced wireless technology in the industrial radio frequency MHz or 915 MHz means that installation work is significantly reduced and cable connections are not required. The wireless-based sensor technology also functions in harsh industrial environments. The supplied lambda/4 antenna with an impedance of 50 ohm can be screwed on directly or fitted externally. If the antenna holder for wall mounting is used with a 3 m antenna cable, the open air range is 300 m. In the receiver, the received measured values are converted, displayed, are available as linear current or voltage signals (0(4) to 20 ma, 0 to 10 V), and can be accessed via an RS485 digital interface. All receiver outputs are galvanically isolated.linkage to higher-ranking systems (e.g. the plant visualization software JUMO SVS3000 or the Modbus master compatible JUMO LOGOSCREEN nt paperless recorder) is possible via the digital interface with Modbus protocol. Operation and configuration can be performed via the keypad in conjunction with a 2-line LCD display, or with a setup program for greater convenience. This allows parameters such as filter constants, offset, alarms, and drag indicators (minimum and maximum value memory) to be set separately for each channel. For this purpose, a plug is provided on the front for a PC interface with TTL/RS232 or USB/TTL converter for connecting the receiver and the PC. The receiver in the mounting rail case is intended to be fitted on a DIN rail 35 mm 7.5 mm according to DIN EN The screw terminals for the electrical connection are arranged in different levels. The conductor cross section may not exceed 2.5 mm Block diagram Figure 1: Receiver block diagram 8

13 3 Basic principles 3.1 Wireless technology The characteristic framework conditions for each transmission system include the available band width in the electro-magnetic spectrum and the maximum admissible transmission capacity. These parameters define the channel capacity. The main selection criteria for the frequency range to be used include the requirement of a long range, interference immunity, and the option of applying a customized transmission protocol in a public frequency band. The focus when selecting the possible communication technologies is placed on minimizing the size of the transmitting and receiving circuit as well as the power consumption, on enhancing the transmission safety and the transmission stability, and on saving costs for the technology involved. Using a wireless connection essentially results in lower costs, greater flexibility and mobility, and easier handling. Taking into account the current applicable legislative texts and the available standards and industry standards, a wireless solution without a generally specified protocol has been selected for use of the Wtrans system on the MHz radio frequency (Europe) or 915 MHz radio frequency (America, Canada, Australia, and New Zealand). In certain areas, there are strict regulations that apply for this industrial radio frequency with regard to duty cycle, channel distribution, and transmission power. The various subdivisions within this frequency band are shown in Figure 2 below. Figure 2: Subdivision of the 868 MHz frequency band The ERP power value (ERP: equivalent radiated power), which is plotted on the Y-axis, represents the permitted transmission power in relation to a lambda/2 dipole gain. The transmission power is only generated for a very short period while using the duty cycle, during the transmission pulse with a small pulse width. The duty cycle in percent indicates the duration of a transmitter's transmissions based on 1 hour. The overall transmission time can be divided across several transmission intervals. The duty cycle thus specifies the ratio between the transmission time and the overall time, and is specified in percent. The duty cycle is also called the pulse-to-pause ratio or mark-to-space ratio. 13

14 3 Basic principles If, for example, the transmission duration of a signal is 5 ms followed by a 995 ms transmission pause, the duty cycle is derived from the following calculation: t ---- S t G = ms = = 0.5 % 1000 ms 3.2 General information about wireless transmission Wireless signals are electro-magnetic waves, the signal of which weakens during travel from the transmitter to the receiver (this is referred to as path attenuation). The field strength reduces inversely proportional to the square of the distance between the transmitter and receiver. In addition to this natural range restriction, a reduced range may also be the result of the following causes: Ferroconcrete walls, metallic objects and surfaces, heat insulation, or windows with vapor deposited metal layer reflect and absorb electromagnetic waves and, for this reason, a dead spot is formed behind. The antenna is installed at an insufficient height; install as high as possible above the floor and ensure a line of sight between the transmitter and receiver. The following values are reference values relating to permeability of wireless signals: Material Permeability Wood, plaster, glass uncoated 90 to 100 % Brickwork, press boards 65 to 95 % Armored concrete 10 to 90 % Metal, aluminum lamination 0 to 10 % The maximumrange between the transmitter and receiver is 300 m in the open air when using the antenna holder for wall mounting on the receiver side. Optimum reception is achieved when there is a clear line of sight between the transmitter and receiver. When installing the receiver in a control cabinet or behind concrete walls or ceilings, always use the antenna holder for wall mounting and antenna cable on the receiver side. TIP! The device manufacturer's antenna holder for wall mounting is specially designed for the lambda/4 antenna and ensures optimum reception quality. Antenna holders for wall mounting not produced by the device manufacturer may disrupt the reception and cannot guarantee optimum reception. TIP! The device manufacturer's antenna cable has an attenuation of 0.8 db/m. From a technical standpoint, we recommend using the shortest possible antenna cable to ensure good reception. 14

15 3 Basic principles 3.3 Reception characteristics of the lambda/4 antenna Alignment of the lambda/4 antenna Figure 3: Spatial directional response pattern of the lambda/4 antenna From the spatial directional response pattern of the lambda/4 antenna, it is clear that optimum reception can only be achieved when the antenna is positioned vertically. From the vertical rod, the reception is nearly identical in all directions. The range at the top and bottom, however, is very limited. The antenna holder for wall mounting can be mounted with the antenna in a vertical position orientated upward or downward, but horizontal antenna installation is not recommended. TIP! To ensure that reception antennas do not interfere with each other, maintain a minimum distance of 500 mm between them for optimum reception. 15

16 3 Basic principles 3.4 Interference Collisions when using too many transmitters When using a large number of transmitters, do not select a transmission interval that is too low, as otherwise the transmission frequency will be occupied unnecessarily. A transmission interval that is too low leads to a very high data volume on the selected frequency, which can lead to collisions with other transmitters. The collision can cause telegrams to be destroyed during wireless transmission. Figure 4: The telegrams of a transmitter reach the receiver without collisions. Figure 5: Telegrams from several transmitters may collide. 16

17 3 Basic principles Fault increase Number of probes Figure 6: Collisions in relation to the number of transmitters at a transmission interval of 1 s As Figure 6 shows, the fault curve increases sharply once 24 transmitters are reached. For this reason, we recommend using a maximum of 16 transmitters for the smallest transmission interval of 1 s. For the factory setting of 10 s, a considerably larger number of transmitters can be used. Estimating the maximum number of transmitters If more than the recommended 16 transmitters are to be used at a transmission interval of 1 s, select a higher transmission interval to prevent an increased fault quota. Example: 16 transmitters with a transmission interval of 1 s = 32 transmitters with a transmission interval of 2 s If the number of transmitters is increased further, this results in the calculation below in the next example. Example: 16 transmitters with a transmission interval of 1 s = 48 transmitters with a transmission interval of 3 s (in theory) However, from a transmission interval of 3 s, the telegram is transmitted twice. For this reason, the number of transmitters to be used is halved. 16 transmitters with a transmission interval of 1 s = 24 transmitters with a transmission interval of 3 s (effective) The same behavior occurs again with a transmission interval of 60 s. From this transmission interval, the telegram is transmitted three times. 17

18 3 Basic principles External transmitters External transmitters may transmit on the same frequency. If, for example, the transmitter and an external transmitter transmit their wireless telegrams at the same time, the telegram is destroyed. Because the transmitters are not able to check their own active transmission while transmitting, no error is detected. Electrical devices In a harsh industrial environment, wireless telegrams cannot be immediately destroyed by such things as frequency converters, electrical welding equipment, poorly shielded PCs, audio/video devices, electronic transformers, or electronic ballasts. Error fade-out The wireless timeout parameter on the receiver side can be used to fade out lost telegrams (either due to external influence or collisions caused by a large number of transmitters) and no error message then occurs. The last received value is thus maintained over 2 to 20 transmission intervals and only then is the wireless timeout alarm activated (display "----"). TIP! In the event of collisions caused by an excessive number of transmitters, observe and, if necessary, correct the factors for "number of probes", "transmission intervals", and, on the receiver, "wireless timeout". 18

It checks whether each wireless telegram received is complete. If the wireless telegram is valid, it is transferred to the processor for further processing, in the same manner as the demodulated measured data. Keypad The function keys enable operation and configuration of the receiver without the setup program. Chapter 6 "Display and key functions", page 35 LCD display In the normal display, the two rows of the LCD display show the current values. In the startup and parameter levels, they facilitate the operation and configuration dialog. Chapter 6 "Display and key functions", page 35 LEDs The top bicolor LED is green when voltage is applied, i.e. the device is operating. It flashes red in the event of a collective alarm. The bottom yellow LED flashes with every valid wireless telegram (data packet) from the transmitter. The flash frequency increases with the number of transmitters. Chapter 6 "Display and key functions", page 35 Setup interface The device is equipped with a setup interface to allow configuration via the setup program. For this purpose, the front features a connector for interface lines with TTL/RS232 or USB/TTL converters for connection to a PC. The setup interface is set with the following values by default: Baud rate: 9600 bit/s, data format: 8 data bits, 1 stop bit, no parity, minimum response time: 0 ms, device address: 1. Chapter "RS485 interface", page 67 Chapter 11 "Setup program", page 81 Actual value calculation for the analog channels General information The wireless telegram detected by the receiver is transmitted to the controller for actual value calculation. Here, the individual measured values are processed. The controller then calculates the respective measured value from the transmitter count values. Linearization and temperature calculation automatically follow the probe characteristic line. 20

21 3 Basic principles Each measured value can be checked for overrange and underrange by means of two limit values. The minimum and maximum measured values are saved in drag indicators. Wireless timeout function The measured values of the probe are monitored via a wireless timeout function. If an individual wireless telegram is missing, the last value received is frozen. If no new wireless telegram is received throughout the entire timeout duration, the measured value is set to "no input value" and the top LED flashes red. Automatic changeover of the interfaces Both interfaces are operated via the same communication module (UART = Universal Asynchronous Receiver Transmitter). If an interface cable is connected to the front setup plug, the device interrupts communication via the RS485 (i.e. the setup connector has priority). Analog outputs A maximum of four analog outputs (current or voltage) are available in the device. The measured value is scaled to the set values for zero point and end value. Measured values outside of these limits are detected as overrange or underrange. In this case, the value set here in the parameter level (value for overrange and underrange) is applied. Chapter 5.2 "Connection diagram", page 32 Chapter 8 "Configuring the receiver", page 49 Relay outputs Depending on the version, the device may have up to two relay outputs. The status that switches relay output 1 or 2 is determined by different control signals. The desired control signal and the output signal (N/C or N/O contact) for each relay can be set in the parameter level. Chapter 5.2 "Connection diagram", page 32 Chapter 8 "Configuring the receiver", page 49 RS485 interface The unit is equipped with an RS485 interface with Modbus protocol to permit connection to higher ranking systems. The baud rate, data format, minimum response time, and device address can be set using the keypad or the setup program. Chapter 5.2 "Connection diagram", page 32 Chapter 8 "Configuring the receiver", page 49 Voltage supply The voltage supply of the receiver is generated with a switch-mode PSU from the mains voltage AC 110 to 240 V. For the galvanic isolation of the output signals, further galvanically isolated voltages for the analog and relay outputs (11.1 to 11.4), the supply for the electronics (11.5), and the interface (11.6) are generated from the secondary voltage of the switch-mode PSU.

23 4 Mounting 4.1 Mounting site andclimatic conditions Receiver Mounting site and climatic conditions The conditions at the mounting site must meet the requirements specified in the technical data. As far as possible, the mounting site should be vibration-free to prevent the screw connections from working loose. The mounting site should be free from aggressive media, e.g. acids and lye, and, if possible, free from dust, flour, and other suspended matter to prevent the cooling slots from being blocked. At the mounting site, ensure a minimum clearance of 100 mm above the device to allow the access to the unlocking slot required for dismounting with a screwdriver. Maintain a minimum clearance of 150 mm if the antenna is fitted directly on the receiver. Several receivers can be fitted next to each other without clearance spacing. (Attention: When several antennas are fitted directly, they may interfere with each other). The ambient temperature range at the mounting site may be -20 to +50 C with a relative humidity of 85 % without condensation Antenna The conditions at the mounting site must meet the requirements specified in the technical data.

Step Action 1 Insert a suitable screwdriver into the unlocking slot and push toward the device. 2 Swing the device out of the DIN rail from below and remove. TIP! At the mounting site, ensure a minimum clearance of 100 mm above the device to allow the access to the unlocking slot required for dismounting with a screwdriver. Maintain a minimum clearance of 150 mm if the antenna is fitted directly on the receiver. Several receivers can be mounted next to each other. 26

27 4 Mounting 4.4 Mounting the antenna The maximum range between transmitter and receiver is 300 m in the open air. The antenna used and its correct positioning are determining factors for both the operating range and reliability of the wireless connection. In practice, a wide range of influences affect the wireless transmission path. For this reason, careful thought should be given to the prevailing conditions at the operating location when selecting the type of antenna mounting. Chapter 3.1 "Wireless technology", page Mounting the antenna directly on the receiver The lambda/4 antenna supplied as standard can be screwed directly to the receiver in a clockwise direction.

43 7 Operating the receiver At the receiver Operation and configuration of the receiver require four keys located at the front which have various functions depending on the menu. The dialog is supported by a 2-line liquid crystal display (LCD). Two light emitting diodes (LEDs) signal various operating statuses. The operation and configuration of the parameters are organized at three different levels: Normal display (display of measured values and signal quality) Chapter 7.1 "Normal display (NA)", page 44 Commissioning/start-up level (channel linking to transmitter ID) Chapter 8.1 "Startup level (In)", page 49 Parameter level (editing of configuration parameters) Chapter 8.2 "Parameter level (PA)", page 55 Each of the two levels can be protected against unauthorized access by a code. Via setup program for PC Configuration via the setup program is more comfortable than using the receiver keyboard. The configuration data can be archived on data carriers and printed. Chapter 11 "Setup program", page 81 43

44 7 Operating the receiver 7.1 Normal display (NA) The normal display is active when the receiver is connected and the voltage supply activated. The measured value of the first transmitter is visible in the top line of the LCD display. The channel designation is visible on the left and the selected unit is on the right in the bottom line of the LCD display. If more than five characters have to be displayed, the display automatically switches to the ticker mode. In the normal display, a maximum of 16 channels and their measured values or the signal quality of the transmitter signal received can be displayed. 7.2 Channels and their Display measured values Linked channels available: Figure 20: Display of all linked channels The and keys can be used to display in succession all channels linked to transmitters and their measured values either in an ascending or descending order. No linked channels available: Figure 21: Display when no linked channels are available The no Link note signals that there are no channels linked to transmitters. 44

45 7 Operating the receiver 7.3 Displaying the signal quality of the received transmitters Figure 22: Display of signal quality The key is used to show the signal quality value of the current channel in percent in the normal display (NA) (see Figure 22, 100 %). The display range between 0 and 100 % is displayed in increments. Increments: 0/20/40/60/80/100 % Display of 0: Remedy: Display of 20 to 40: Remedy: Display of 60 to 100: No transmission signal Chapter 4 "Mounting", page 23 Check transmitter battery, optimize wireless transmission path Insufficient transmission signal Check receiver antenna mounting site Signal quality is sufficient for reliable system operation TIP! The displayed signal quality is calculated from the last five expected transmission intervals. If a telegram is received in all five transmission intervals, the signal quality is 100 %. If only four telegrams are received, the signal quality is reduced to 80 %, etc. Number of telegrams received in the last 5 transmission intervals Display of signal quality % 4 80 % 3 60 % 2 40 % 1 20 % 0 0 % Table 1: Number of telegrams received and signal quality display For optimum positioning of transmitter and reception antenna, we recommend setting a very small transmission interval as a test. This reduces the waiting time for the signal quality display update. 45

46 7 Operating the receiver 7.4 Changing to different levels Figure 23: Changing to different levels Hold the key for > 2 s to change to the startup level (In). The receiving channels of the unit are linked with the transmitter ID here. Hold the key for > 2 s to change to the parameter level (PA). All functions of the receiver and the corresponding parameters are defined here. Key timeout If no key is pressed in these two levels for a period of 40 s, the receiver automatically returns to the normal display (NA). Code request The receiver features one code request for each changeover to the startup level or the parameter level. This code request, however, is not active when delivered. In the parameter level (PA), a code (minimum 1 digit, maximum 4 digits) can be assigned separately for each level (In and PA). Chapter 7.5 "Code request", page 47 46

47 7 Operating the receiver 7.5 Code request Figure 24: Code request for the startup or parameter level The code for changing from the normal display (NA) to the startup or parameter level can be edited either directly or digit by digit. Direct editing Use this process if short codes are generally sufficient (see path II in Figure 24). Procedure: Step Action 1 To change from the normal display (NA) to the startup level (In), hold the key for > 2 s or to change to the parameter level (PA), hold the key for > 2 s. When a code is assigned for the selected level, "CodE" appears on the display. The device waits for a code to be entered (min. 1 digit, max. 4 digits). 2 Edit the code using the and keys. 3 Hold the key for > 2 s to confirm the code entry. If the code is correct, "CodE OK" appears for 0.25 s. The receiver changes to the desired level. If the code is incorrect, "CodE Error" appears for 0.25 s. The receiver returns to the normal display. 47

48 7 Operating the receiver Editing digit by digit The procedure is practical if longer codes are generally required (see path I in Figure 24). Procedure: Step Action 1 To change from the normal display to the startup level (In), hold the key for > 2 s or to change to the parameter level (PA), hold the key for > 2 s. If a code is assigned for the selected level, "CodE" appears on the display. The device waits for a code to be entered (min. 1 digit, max. 4 digits). 2 Initiate code editing with the key. The lower segments of the digit on the right flash. 3 Edit digits using the and keys. 4 To confirm the first digit, press the key. The lower segments of the second digit from the right flash. 5 Repeat steps 3 and 4 until all digits have been edited (min. 1 digit, max. 4 digits). 6 Confirm the code with the key. The lower segments of the digits entered last stop flashing. 7 Hold the key for > 2 s to confirm the code entry. If the code is correct, "CodE OK" appears for 0.25 s. The receiver changes to the desired level. If the code is incorrect, "CodE Error" appears for 0.25 s. The receiver returns to the normal display. TIP! To deactivate, set the code for the startup or parameter level to 0. Chapter "General parameters", page 58 48

49 8 Configuring the receiver 8.1 Startup level (In) The receiver channels are assigned to the transmitters in this level (linkedwith each other). This can be done conveniently using the setup program, or manually via the keypad. The options are described below. Regardless of the method adopted, the following points must be noted: Assign each transmitter ID to a transmitter only once, as the receivers cannot differentiate between several transmitters that have the same ID. A transmitter ID may also only be linked once to each individual receiver. After receiving a wireless telegram, the receiver checks the channels 1 to 16 until it finds a matching link. For this reason, a second channel with the same link would not receive any input values. If for some reason the actual value of a channel must be emitted on two analog outputs simultaneously, this channel must be configured in two analog outputs with a selector. Chapter 3.6 "Data flow diagram", page 22 49

50 8 Configuring the receiver Convenient selection of the received transmitter ID from the link list and assignment to a channel Figure 25: Selection of a received transmitter ID from the link list and assignment to a channel TIP! The link list contains the non-linked IDs received in the last ten minutes. Transmitter IDs that have already been linked are no longer displayed in the link list. 50

51 8 Configuring the receiver Use this process if both the transmitters and the receiver are active. Each receiver registers all transmitters that it receives but has not linked itself in a link list with a maximum of 25 entries. This list is automatically generated. New transmitters are added automatically. If a transmitter does not signal for a period of 10 minutes, it is removed from the list. When it is opened, this list is "frozen". The ID received last is given first. It can be used to link the received transmitter ID with the individual receiver channels as described below. Procedure: Step Action 1 Hold the key for > 2 s to change from the normal display to the startup level (In). 2 Select the channel of the receiver to be linked using the or key (in Figure 25, channel 3). 3 Call up the link list with the key. The link list is frozen and the transmitter IDs are sorted by time at which they were received. The channel is displayed in the top line of the display (in the example 3). The currently assigned transmitter ID flashes in the bottom line. 4 Use the key to select the transmitter ID to be linked. The selected transmitter ID flashes. 5 Hold the key for > 2 s to link the transmitter ID to channel 3. The selected transmitter ID stops flashing. The "Link" information appears for 0.25 s in the bottom line of the display. 6 To return to the normal display, hold the key for > 2 s or use the 40 s key timeout. The display returns to the channel that was displayed last in the normal display. All channels can be linked with the received transmitter IDs in the manner explained above. 51

52 8 Configuring the receiver Manual assignment of a transmitter ID to a channel Figure 26: Manual assignment of a transmitter ID to a channel Use this process if the receiver is to be set up before the transmitters are commissioned. The transmitter ID (max. 5 digits) is applied to the the transmitter ex works and can be manually entered for a receiver channel. You can use the function keys to assign the relevant transmitter to a receiver channel. This ensures clear assignment of a transmitter (the measured value) to the selected receiving channel. Proceed as described below to link the transmitter. Procedure: Step Action 1 Hold the key for > 2 s to change from the normal display to the startup level (In). The display changes to the startup level. 2 Select the receiver channel to be linked using the or keys (in Figure 26, channel 2). 0 appears on the right in the bottom line of the display. 3 Initiate editing with the key. The lower segments of the number 0 on the right flash. 4 Use the or keys to edit the digits. 5 Use the key to confirm the first digit. The lower segments of the second digit from the right flash. 6 Repeat steps 3 and 4 until all digits have been edited (minimum 1 digit, maximum 5 digits). 7 Confirm the transmitter ID to be linked with the key. The entire transmitter ID that was entered flashes. 52

53 8 Configuring the receiver Step Action 8 Hold the key for > 2 s to link the transmitter ID to channel 2 (see Figure 26). The entered transmitter ID stops flashing. The "Link" information appears for 0.25 s in the bottom line of the display. 9 To return to the normal display, hold the key for > 2 s or use the 40 s key timeout. The measured value of the transmitter linked to channel 1 is displayed in the top line of the display. The channel designation 1 and the unit re-appear in the bottom line. All other transmitter IDs can be assigned directly to the desired channel in the manner explained above. 53

54 8 Configuring the receiver Assignment of a transmitter ID to a channel via an interface Use this process if receiving channels are to be linked with constantly changing transmitters. This could be necessary, for instance, for continuous furnaces or production lines that require a large number of transmitters that move through the system and are read out at one single channel of a stationary receiver. Linking can then be carried out, for example, by a PLC that has information about the product that is currently moving through the system. Interface description B "Linked transmitter IDs in the Modbus address list" Pre-configuration of all transmitter IDs using the setup program This process can also be used if the receiver is to be set up before the transmitters are commissioned. To do this, tick "Channel active" in the receiver channels of the setup program and insert the ID specified on the transmitter for "Transmitter ID". The setup data can be transmitted to the receiver in a block and saved as a file Configuring customer-specific transmitter IDs on the transmitter side Use this process if there are compelling reasons for not using the factory default transmitter IDs. Instead of the default transmitter IDs, the transmitter can be assigned a customer-specific transmitter ID. This requires the setup program, as the customer-specific transmitter ID must be stored in the transmitter beforehand using the setup interface. It should be clearly visible and durably affixed to the transmitter, or noted and kept at a different place. The customer-specific transmitter ID is linked on the receiver side in the same manner as the default transmitter IDs. Chapter "Convenient selection of the received transmitter ID from the link list and assignment to a channel", page 50 Chapter "Manual assignment of a transmitter ID to a channel", page 52 The difference in the procedure is that the ID assignment in pairs can also be changed on the transmitter side, which permits the use of low, easy to remember IDs, for example 1 to 16. However, it must be ensured that IDs are not assigned twice as otherwise the receiver cannot differentiate between the transmitters that have the same ID. 54

55 8 Configuring the receiver 8.2 Parameter level (PA) Figure 27: Browsing and jumping between groups The parameter level comprises an extensive list of editable parameters that are grouped in a user-friendly manner. The key functions shown enable quick browsing up and down, or jumps from one group to another. This level is used to adapt the receiver to its task. Settings can be selected in the individual parameters or values can entered within the factory default limits. All parameters are described in Chapter 9 "Term definition", page 65 to keep instructive and descriptive texts separate from each other in the following tables. TIP! Default settings are shown in bold. 55

56 8 Configuring the receiver Recommended procedure: Step Action 1 Read the parameter descriptions in Chapter 9 "Term definition", page Enter the desired settings/values in the right-hand column! of the following tables. 3 Individually select and edit the parameters in turn. This is the only way to ensure parameter entry within the factory default key timeout of 40 s. After the timeout, the receiver automatically returns to the normal display. The selections/settings that were performed before this point remain unchanged. CAUTION! Following each parameter change, wait at least 15 s before switching the receiver off as otherwise the change will not have been saved. This takes place automatically in the background. Premature deactivation results in a configuration data checksum error at the next switch-on. Bit 0 of the Error parameter is set, the upper LED flashes red as a result of the collective alarm, and the parameters are changed to the factory settings. 56

67 9 Term definition RS485 interface TIP! Modbus B interface description (The Modbus interface description is available as a free download on the Internet at Baud rate Transmission speed of the RS485 interface. If a master (PC or PLC) is connected to the interface, select the same baud rate on the master side. Data bits/parity/stop bits RS485 interface data format If a master (PC or PLC) is connected to the interface, select the same data format on the master side. Minimum response time The receiver adheres to the minimum response time following a data request before sending a response. The response time is required by the master for the RS485 interface in order to switch the interface drivers from transmit to receive. Device address The receiver can be accessed with the set unit address via the RS485 interface. For this interface, the device address of the receiver may only appear once within a connection (several devices on one bus). CAUTION! These settings only relate to the RS485 interface. The setup connector is operated independently of these parameters with the fixed settings for transmission speed: 9600 baud, data format: 8n1, minimum response time: 0 ms, and device address: 1. Customer replacement actual values The current display values can be read out from a receiver by a Modbus master via the addresses (hex) 00E7 to In the event of an error (timeout, overrange, underrange, etc.) it reads a very large value (e.g for wireless timeout see chapter of B "Modbus interface description") via these addresses. The new customer replacement actual values for the addresses (hex) 0407 to 0425 are intended for all users who are unable to evaluate these large values with their Modbus masters. In a normal case (no errors present), the customer replacement actual values contain the same values as the display values. In the event of an error, the customer replacement actual value programmed in the receiver is transmitted. This allows the user to identify errors. 67

Chapter 2.2 "Order details", page 10 Output variable (Ax.SEL) The actual value to be issued at the selected output is defined here (see Figure 29, item 6). In addition to the actual values of the 16 wireless inputs, four Modbus remote control values are available in the analog selector. Zero point (Ax.Zer) and end point (Ax.End) The zero point and the end point (see Figure 29, item 3 and item 4) permit the entire measuring range or part of it to be displayed at the output (e.g. 0 to 200 C). Error behavior (Ax.Err) The type of error message to become active under the following conditions is set here (see Figure 29, item 7): Underrange/overrange Probe short circuit Probe/cable break Alarms ErHi (positive signaling) and ErLo (negative signaling) may be used. The behavior of the output signal in the event of underrange or overrange is shown in the following table. 68

70 9 Term definition Relay outputs 1 to 2 Figure 30: Behavior of the relay outputs 1 to 2 Performance (Kx.Mod) This function defines how therelay output is operated. N/C and N/O contacts are available (see Figure 30, item 2). Not every receiver type provides relay outputs. Chapter 2.2 "Order details", page 10 Control signal (Kx.SEL) The control signal (see Figure 30, item 1) defines the status used to switch relay output 1 or 2. The following conditions can be set in the binary selector: Relay output inactive (not assigned) The relays remain in their configured basic status (no/nc). Wireless timeout, channel 1 to 16 A relay is switched when the wireless timeout is exceeded. The wireless timeout is a configurable alarm bit which is set when the wireless signal of a linked transmitter has not been received for a long time. Analog alarm 1 and 2, channel 1 to 16 A relay is switched when limit value alarm 1 or 2 is activated. Low battery, channel 1 to 16 A relay is switched when a transmitter battery needs to be replaced. Relay status 1 and 2 A relay is switched when it is accessed by another relay. Due to the fact that the relay outputs in the receiver have only two pins, it is possible to make one changeover contact out of two relays: for example relay 2 is configured as a logical inverter (N/C contact). 70

71 9 Term definition Collective alarms A relay is switched when any alarm is activated. Collective alarms can be: OR link of all individual alarms Wireless timeout, channel 1 to 16 Analog alarms 1, channel 1 to 16 Analog alarms 2, channel 1 to 16 Low battery, channel 1 to 16 Save errors detected with power ON Chapter 8.2 "Parameter level (PA)", page 55 Remote control values BOOLEAN 1 to 4 A relay is switched when the remote control value is set to ON. Remote control values are controlled via an interface. Fixed value ON/OFF Depending on the selection, a relay is activated or deactivated. 71

72 9 Term definition Modbus remote control values FLOAT 1 to 4 Remote control values can be transmitted via the interface by a Modbus master (e.g. PLC) and displayed and processed by a receiver. Operating manual B "Modbus interface description" If the analog outputs are directed to these control variables via a selector, the Wtrans receiver can also be used as a 4-channel analog output module. This means that control variables calculated by a PC program can be supplied in the process. Simultaneous operation as a 16-channel wireless reception module and 4-channel analog output module is also possible (see Figure 31). Figure 31: PC with visualization/control software 72

73 9 Term definition 9.2 Channel-specific parameters Wireless telegram timeout [Wireless timeout (xx.tmo)] This is the number of transmitter intervals during which one new probe value must have arrived. The set transmission interval of the transmitter is transmitted with the wireless telegram. When the first telegram is received, this value is saved in the receiver and the wireless timeout monitoring function is activated. If no new value from the transmitter is received throughout the entire timeout period, the measured value is set to "no input value", the alarm bit "Wireless timeout" of the channel is set, and the top LED flashes red. Offset (xx.off) This offset value (actual value correction) is added to the measured input value with the correct sign. This permits a correction in the "+" as well as the "-" direction. Examples: Measured value Offset (actual value correction) Displayed value CAUTION! After an offset change, you should perform the following steps if necessary: 1. Reset the drag indicator. 2. Check the scaling of the analog outputs. 3. Check the settings of the limit value alarms. Filter time constant (xx.df) This parameter is used to adapt the digital input filter to the task. In the event of a signal jump, 63 % of the alterations are acquired after 2 filter time constants. If the filter time is long, it means: High attenuation of interference signals Slow reaction of the actual value display to actual value changes Low limit frequency (2nd order low-pass filter) Decimal place (xx.dp) The position of the decimal point is selected here. Between 0 and 2 decimal places can be selected or the automatic display (one decimal place as standard) can be used. If the actual value exceeds the measurand that can be displayed with the decimal places, the decimal place(s) are not used. Customer-specific linearization Four customer-specific linearizations are available in addition to the linearization that follows the input signal in a linear manner. The corresponding linearization tables must be created with the setup program. In order to use the customer-specific linearization, a suitable transmitter must be linked and the transmitter sensor type must be configured as Resistance transmitter, Potentiometer, Voltage, or Pressure. 73

74 9 Term definition The parameter is only available for receivers with a hardware version of 1 or above, or with a device software version that is equivalent to or above. Chapter 2.1 "Nameplate", page 9 Chapter 11.5 "Customer-specific linearization", page 87 Unit for resistance transmitter types, potentiometer, or voltage One of 16 units (17 units with device software version and above) can be selected here. The unit is shown in the receiver display. The parameter is only available for receivers with a hardware version of 1 or above, or with a device software version that is equivalent to or above. Chapter 2.1 "Nameplate", page 9 Chapter 11.5 "Customer-specific linearization", page 87 Unit for pressure transmitter types One of 7 units can be selected here. The unit is shown in the receiver display. In addition to this unit, the numerical value for the pressure is also automatically converted here (except for "free text entry"). The parameter is only available for receivers with a hardware version of 1 or above, or with a device software version equivalent to or above. Chapter 2.1 "Nameplate", page 9 Chapter 11.5 "Customer-specific linearization", page 87 Scaling active Scaling is performed if the parameter is set to "On". The parameter is only available for device software version or above. Scale start, scale end For transmitters where the sensor type is configured as Resistance transmitter, Potentiometer, Voltage, or Pressure, the input measuring range (e.g. 0 to 50 mv) can be scaled to a range defined by the user (e.g. 0 to 250). The corresponding unit is configured with the Unit parameter. The parameter is only available for receivers with a hardware version of 1 or above, or with a device software version that is equivalent to or above.

75 9 Term definition Alarm type 1/2 (xx.a1m/xx.a2m) Figure 32: Setting the alarm functions High alarm (HiAL) An alarm is issued when the positive limit value is exceeded (after the alarm delay time has elapsed), not taking the hysteresis into account (see Figure 32, item 1). Reset conditions: return to a value below the positive limit value minus hysteresis. Low alarm (LoAL) An alarm is issued when the negative limit value is not met (after the alarm delay time has elapsed), not taking the hysteresis into account (see Figure 32, item 3). Reset conditions: return to a value above the negative limit value plus hysteresis. Limit value alarm 1/2 (xx.a1l/xx.a2l) The limit value for the selected alarm type 1 and 2 is set here (see Figure 32, item 4 and item 6). Hysteresis (xx.hys) The hysteresis is the difference between the set limit value alarms. 1 or 2 is always set as a positive value for the Max. alarm and Min. alarm (see Figure 32, item 5). Alarm delay (xx.ald) This parameter is used to suppress short-term faults (see Figure 32, item 2). The alarm signal is activated only after the set time has elapsed if there is still a limit value overrange or underrange. TIP! The alarms can be configured as a window function (min/max) or as pre-alarm or main alarm (min/min or max/max). 75

76 9 Term definition CAUTION! Alarm in the event of probe break or probe short circuit: Even probe break (display "oooo") or probe short circuit (display "uuuu") values which indicate a definite fault only lead to an alarm bit being set and consequently to a collective alarm with a red flashing LED if at least one alarm (either LoAL or HiAL) has been configured. If you only wish to receive a probe break/probe short circuit alarm and do not require any limit value monitoring, activate an alarm using a limit value outside of the range of occurring actual values. Example: Your actual value may be between -10 and +200 C. Pure probe break/probe short circuit alarms can be achieved, for example, using a HiAL configuration with a limit value of 300 C or a LoAL configuration with a limit value of -100 C. Upper/lower drag indicator (xx.min) and upper drag indicator (xx.max) The minimum and maximum values for each channel are saved and shown on the display when requested. In this context, overrange and underrange are not taken into account. These values can be reset using the keypad or interface. Once the drag indicator has been reset, the current value is adopted and the drag indicator function restarts. Chapter "Channel-specific parameters", page 62 Chapter 10 "Displaying and resetting a drag indicator", page 77 Figure 33: Chronological sequence of drag indicator functions Figure 33 shows the chronological sequence of the lower (xx.min) and upper (xx.max) drag indicator functions. The value Max.1 is saved in the first positive half-wave of the actual value curve, value Min.1 is saved in the first negative half-wave. The keypad can be used to reset these values; in the example this occurs at t Reset. Once the drag indicator has been reset, the current value is adopted (Max.2 = Min.2). The drag indicator function restarts. The next saved values are Max.3 and Min.3. 76

77 10 Displaying and resetting a drag indicator The drag indicator values of channels 1 to 16 cannot be shown in the normal display. To do this, switch to the parameter level and to the channel-specific parameters there. At the end of the selection list of groups 1 to 16 (channels 1 to 16), there are three parameters that are relevant for the drag indicator function (see table). Parameter Bottom line display Top line display Chapter 8.2 "Parameter level (PA)", page 55 Value range/ selection Drag indicator, lower xx.min to Display only, cannot be edited Minimum value drag indicator with automatic decimal point Drag indicator, upper xx.max to Display only, cannot be edited Maximum value drag indicator with automatic decimal point Reset drag indicator xx.res 0 1 Drag indicator: do not reset reset TIP! To use this function, you must know how to jump between groups 1 to 16 (channels 1 to 16) and how to browse step-by-step between parameters in these groups. The display shows the two upper and lower drag indicator values in 2 lines. The bottom line shows the drag indicator type xx.min or xx.max. In the device display, xx is replaced by the numbers 1 to 16, which indicates the selected channel. The top line shows the corresponding measured value. In the case of the "Reset drag indicator" parameter, the bottom display shows xx.res (for reset). This parameter offers the following setting options: No reset, i.e. the drag indicator function of the selected channels is retained Reset, i.e. both drag indicator values (Min and MAX) are deleted The next two pages describe how to display and reset the drag indicator values of channels 1to16. 77

79 10 Displaying and resetting a drag indicator Procedure: Step Action 1 Hold the key for > 2 s to leave the normal display (NA) and move to the parameter level (PA). In the bottom line, the display shows the first general parameter the software version (SWVER). 2 Hold the key for > 2 s to jump to a channel-specific parameter. In the bottom line, the display shows the 1st parameter for the 1st channel timeout of the wireless telegram [wireless timeout (01.Tmo)]. 3 Use the key to browse to the lower drag indicator parameter (01.Min) of the 1st channel. In the top line, the display shows the minimum value of the 1st channel. 4 Use the key to browse to the upper drag indicator parameter (01.MAX) of the 1st channel. In the top line, the display shows the maximum value of the 1st channel. 5 Use the key to browse to the "reset drag indicator" parameter (01.RES) of the 1st channel. The display shows "0", which means that the drag indicator is active. 6 Use the key to select the "reset drag indicator" parameter. The "0" display flashes. 7 Use the key to select the "reset drag indicator" parameter. The display shows a flashing 1 in the top line. This selection can be reversed using step 8. 8 Use the key to select the "do not reset drag indicator" parameter. The display shows a flashing 0 in the top line. 9 Hold the key for > 2 s to apply the "reset drag indicator" function as in step 7 (or "do not reset drag indicator" function as in step 8). The display shows Stor (storage) for 0.25 s and then jumps to "reset drag indicator" (01.RES). 79

81 11.1 General information about the setup program 11 Setup program The configuration data of the receiver and transmitters can be archived in a single file on data storage media and can be printed and kept on record. You can use the setup program to overwrite changed parameters with the factory default settings at any time. The receiver and the PC are connected via a PC interface (USB/TTL or TTL/RS232). Figure 35: Setup program The setup program enables convenient and clearly structured adjustment of the numerous device parameters. If settings have been made once, they can be saved on data storage media as files and transferred to other devices as identical settings. If there is an online connection to the device, the bottom section of the screen the "diagnosis window" shows actual values and further informative values for all channels in parallel. TIP! For configuration, the receiver must be connected to the voltage supply. Chapter 5.2 "Connection diagram", page 32 81
